Here a domain name doesn't show up, just an IPv4 address. I have started to  
add the IP's to block them. I was looking for a way to limit x connection 
attempts from the same IP address within x seconds. And decided to use the 
command line:

iptables -A INPUT -p tcp --dport 23 -i eth0 -m state --state NEW -m recent
--update --seconds 10 --hitcount 3 -j DROP

Which has seemed to help as my busy nodes issue isn't as bad as it was. At 
least BBBS looks to be freeing up the nodes quicker.
